At the moment there are alot of crays around but in saying that you have to be very aware of the spawning and re-shelling of these amazing creatures. An experienced diver can tell a male from a female by its posture, leg size , body shape and tale width if visible. A newley shelled crayfish will be clean of barnicles and fresher in colour - often more orange than brown. Different coastal areas host different spawning and shelling periods so there's always descent rocks to dive on.
